glpiaims. (01. 18228) I This invention relates to sewer 'flushers. One such type generally used in cleansing sewer traps, drains and the like is called the bag type flusher. This style consists of a bag which is placed in a pipe tobe flushed and then inflated so that it will therebysecure itself within said pipe. A liquid, such as water, is then forced through the bag into the pipe. Such a type flusher is difficult to use since when the bag is inserted in the pipe the liquid outlet may become lapped or tangled in the bag and thereby becomes a trial and error device. Another disadvantage is that when the bag is inserted in the pipe, it is only adapted to flush a pipe by discharging the liquid from its end. In order to overcome the foregoing features:

One of the objects of this invention is the provision of a flusher adapted to discharge water from its end and also its side so that pipes at substantially any angle to each other may be flushed.

Another object of this invention is the provision of a flexible flusher provided with a plurality of liquid conduits adapted to direct a flowing stream of liquid into various directions in a drainage system.

A further object of this invention is the provision of a flexible flusher adapted to be inflated or deflated so as to secure itself within a pipe or to be easily removed from such pipe.

Other objects and features will more fully appear from the following description and accompanying drawings in which: Fig. 1 is a sectional view of a pipe showing in elevation the flusher disposed therein; Fig. 2 a longitudinal sectional View of a flusher disposed in pipe; and Fig. 3 is a view similar to Fig. 2 but showing the flusher assembled for lateral flushing instead of axial flushing as disclosed in Fig. 2.

Referring to the drawings, the sewer flusher is designated by the numeral l and is made of a strong flexible material such as rubber or the like. The flusher consists of a cylinder 2 provided with a top 3 and a bottom 4. A flexible pipe 5 is disposed in the flusher and has its upper end secured to the top and its lower end to the bottom of said flusher. The top portion of pipe 5 is greater in diameter than the remaining portion so as to increase the pressure of water flowing downwardly through said pipe. A water hose 6 is threadedly mounted and secured in the top 3 of said flusher and registers with pipe 5 to receive a flow of water from said hose. The lower portion of pipe 5 is adapted to accommodate a plug 1 (Fig. 3) to prevent the flow of a liquid or water through the bottom of the flusher. A flexible tubular branch or pipe 8 is also disposed within the flusher and has one of its ends connecting pipe 5 and the other or outer end mounted in the side 2; said side being reinforced about said outer end by flexible material 9. The outer end of pipe 8 is adapted to accommodate a plug [0 in threadable' fashion so as to prevent the flow of water through said pipe.

A chamber H is formed within the flusher by the side, top, bottom and said pipes, and a channel l2 in top 3 is adapted to accommodate an air hose It to provide the supplying and releasing of air to and from said chamber respectively for inflationary and deflationary purposes.

The device functions as follows: If it is desired to flush a sewer trap, pipe 8 is sealed by plugjll and the flusher is inserted in a sewer trap I4 (see Fig. 2). The flusher being flexible and in a deflated condition is easily inserted. Compressed air is then supplied into chamber ll through pipe l3 until the flusher is sufficiently inflated to prevent displacement between said trap l4 and the flusher; such air being kept at a pressure to maintain such condition. When the flusher is securely disposed, as aforesaid, in the sewer trap, water under pressure is then supplied through water hose 6 and pipe 5 from whence it passes into the trap to flush and clean the latter.

After the sewer trap has been flushed and cleaned the compressed air in chamber I l is then released through pipe l3 causing the flusher to deflate and the latter may then be removed from said trap.

It is obvious from the foregoing that the flusher, as illustrated in Fig. 2 is for use in sewer traps and waste pipes when it is desired to direct a flowing stream of water directly'into the trap or pipe.

As is often the case, a trap or pipe 15 (see Fig. 3) is provided with a waste pipe I 6 secured at an acute angle to the former and connecting with the street main. It is obvious that the existence of such a condition will not permit the flushing of pipe I6 through pipe 5 as illustrated in Fig. 2; therefore, pipe 8 is left open and pipe 5 is sealed by plug I. Air is then supplied to the chamber and water under pressure is supplied through water hose 6, pipe 5 and pipe 8 from whence it enters pipe I6 to flush and clean the latter.

It is thought obvious from the foregoing that when plug I0 is disposed in pipe 8 the water or liquid will be directed into the pipe from the end of the fiusher; while when plug 1 is mounted in pipe 5 such liquid will be directed from the side of the flusher, thus providing for the flushing of pipes connected at various angles to adjoining pipes.

Having described this invention, what is claimed is:

1. A sewer flushing device, comprising a ho]- low inflatable body of yieldable material being substantially cylindrical and having substantially thickened top and bottom walls and a thin flexible expansible side wall, in combination with a tubular member connecting the top and bottom walls in spaced relation from the side wall, the wall thickness of said tubular member being thicker than the side wall and thinner than the top or bottom wall, said tubular member having a laterally extending tubular branch member establishing communication with the first named tubular member and the exterior of the side wall, in further combination with an interchangeable plug for the exits adapted to be used alternatively for the first named tubular member and for the branch member.

2. A sewer flushing device, comprising a hollow inflatable body of yieldable material being substantially cylindrical and having substantially equally thickened top and bottom walls and a 4 thin flexible expansible side wall, in combination with a tubular member connecting the top and bottom walls in axial relation thereto and to the side wall, the wall thickness of said tubular member being less than that of the top wall and more than that of the side wall, said tubular member having a laterally extending tubular branch member connected thereto and establishing communication with the exterior of said side wall and the first named tubular member, said tubular member and said branch member having exits, in further combination with an exit plug adapted to be used interchangeably with either exit.
